DETAILED DESCRIPTION

Specific embodiments of the invention will now be described in detail with reference to the accompanying figures. Like elements in the various figures are denoted by like reference numerals for consistency.

In the following detailed description of embodiments of the invention, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to one of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

In general, embodiments of the invention provide a method and system for controlling a call in a controlled facility. The call may be a single one-to-one call or a multiparty call. A multiparty call is a telephone call having more than two parties. For example, an inmate may call a second party, and the second party may call a third party. The second party may stay on the multiparty call or may leave the multiparty call. Further, the second party may be a person or software. The call may include text, audio, and video. Embodiments of the invention include functionality to determine whether an inmate is violating any rules during the call. For example, one rule may be that inmates may not contact inmates in other controlled facilities. In such an example, a controlled facility adds a tone to the audio in the call. When another controlled facility receives the call, the controlled facility may detect, based on the tone, that the call is from another controlled facility and, thus, that the inmate is violating the rule.

Embodiments of the invention may include interactions with a secure social network. In one or more embodiments of the invention, a secure social network is a network application that facilitates and secures the exchange or transmission of information between two or more parties in which at least one of those parties is subject to special security or law enforcement restrictions or otherwise resides in, or is subject to the controls of a controlled facility. Exchanged or transmitted information may be member generated, such as a photo or a video message, or it may be member-curated, such as a news headline, a famous quote, or a sports score.

FIG. 7 shows a schematic diagram of a system including a network application (700) and a database server (702). The network application (700) may execute or be a part of application server (118) in FIG. 1. Similarly, the database server may be database server (120) in FIG. 1. Alternative configurations may also be used. For example, either, both, or part of the network application (700) and database server (702) may be located in the controlled facility. The network application (700) and database server (702) are discussed below.

In one or more embodiments of the invention, a network application (700) is a software application for connecting inmates and administrators to a network. For example, the network may be a telephone network (not shown) or a secure social network (not shown). The network application (700) may include a party verification module (704), a call analysis module (706), a connection module (708), and a user interface (710). Each of these components is discussed below.

In one or more embodiments of the invention, the party verification module (704) includes functionality to verify parties to a multiparty call. Specifically, the party verification module (704) includes functionality to verify that the inmate is authorized to call the numbers called in the multiparty call, to confirm the identity of parties on the call, and to verify that parties on the call are authorized. In one or more embodiments of the invention, the party verification module (704) includes functionality to perform a voiceprint analysis of parties on the call.

In one or more embodiments of the invention, the call analysis module (706) includes functionality to analyze the multiparty call. Specifically, the call analysis module (706) includes functionality to analyze the discussion of the call for inappropriate content, determine whether a crime is being discussed, compare call fingerprints, and perform other such acts. The call analysis module (706) may include a tone detector (not shown). A tone detector includes functionality to detect when a call has a tone from a controlled facility. Thus, for example, the tone detector may detect inmates in different controlled facilities talking even when one of the inmates calls the other inmate through an intermediary. In one or more embodiments of the invention, each tone is unique to a controlled facility. Specifically, each controlled facility may have a distinct and unique tone in one or more embodiments of the invention. Alternatively, the tone may be identical for each controlled facility. In one or more embodiments of the invention, the call analysis module (706) may include functionality to perform data mining on connection parameters of the call. For example, the connection parameters may include an inmate identifier of an inmate making the call, the phone numbers called, the time of day of the call, and other parameters of a call.

The connection module (708) includes functionality to connect the inmate to a multiparty call. Specifically, the connection module (708) includes functionality to receive a request for a multiparty call and implementing the multiparty call. The connection module (708) may include a tone generator (not shown) that includes functionality to generate a controlled facility tone. In one or more embodiments of the invention, the connection module (708) may include functionality to generate a fingerprint for the call. A fingerprint is a unique identifier of the call. For example, the fingerprint may be the first, middle, or last couple of seconds of a call.

In one or more embodiments of the invention, a user interface (710) includes functionality to interface with an investigator or administrator. For an administrator or reviewer on the call, the user interface includes keypad, voice or other buttons to control the audio on the call, individually controlling the audio of one or more parties the call, reducing background noise or performing other actions. Further, in one or more embodiments of the invention, the user interface (710) may include functionality to display a pictures of the parties to the call, a picture of the party currently talking in the call, present call parameters (e.g., statistics). In one or more embodiments of the invention, the user interface (710) may include functionality to display a social networking profile of each party on the call, display details about an inmate's incarceration (e.g., booking date, charges, convictions, gang affiliations, disciplinary actions). The user interface (710) may include functionality to display familial and gang affiliations visually, with differently colored or dashed (or otherwise visually distinguished) lines connecting members of each affiliation.

Although not shown in FIG. 7, the network application (700) may include an authentication module. In one or more embodiments of the invention, an authentication module includes functionality to authenticate individuals to the desired network. For example, the authentication module may include functionality to receive authentication credentials, and determine whether the authentication credentials match stored credentials for the individual. The authentication credentials may be user name, password, voiceprint authentication, face verification information, identifying body marks and features information, retina verification information, palm or fingerprint verification information, or any other type of credential for authentication.

Continuing with FIG. 7, the network application (700) is operatively connected to the database server (702). The database server (702) includes functionality to store information for the network application (700). For example, the database server (702) may store an inmate account (712) for each inmate, party voiceprint data (718), audit data (714), and saved communications (716). Each of the stored data is discussed below.

Continuing with the database server (702), an inmate account (712) is an account storing information about an inmate. For example, an inmate account (712) may include a telephone connection list (720) and incarceration information (722). Additionally, although not shown in FIG. 7, the inmate account may also include administrative information, such as name, birthdate, inmate identifier, and other information. Additionally or alternatively, the inmate account (712) may include authentication credentials (not shown) for the inmate to authenticate him or herself to the network application (700).

The telephone network list (720) corresponds to a list of contacts of the inmate for communication via the telephone network. In one or more embodiments of the invention, before being allowed to communicate with the contacts, the contacts must be approved. Further, although an inmate may communicate with contacts in the inmate telephone network list and the inmate secure social network list, the contacts may not be approved in accordance with one or more embodiments of the invention. Specifically, the inmate telephone network list and the inmate secure social network list may include unprocessed contacts, filtered contacts, and/or approved contacts.

An unprocessed contact is a contact that has not been vetted or checked to determine whether communication with the unprocessed contact is prohibited. A filtered contact is a contact that is not outright prohibited for communication. An approved contact is a contact that has been vetted and with whom the inmate may communicate. For example, unprocessed contacts may be filtered to remove contacts that are known gang members, are inmates, are wanted criminals, or have other attributes, which make communication with such contacts outright prohibited. In one or more embodiments of the invention, the filtering process may include comparing the contact with lists of prohibited people. In some embodiments, the remaining contacts after the filtering processed are approved contacts. In alternative embodiments, filtered contacts may have to be vetted (e.g., go through an identification and/or approval process) to be approved contacts. The vetting may include performing background checks on the contact and confirming the identity of the contact. In one or more embodiments of the invention, rules of the controlled facility define whether filtered contacts must be vetted in order for the inmate to communicate with the approved contacts. Whether a contact is an unprocessed contact, filtered contact, or approved contact may be maintained as an attribute defined for the contact in the inmate account.

In one or more embodiments of the invention, the incarceration information (722) corresponds to information about an inmate's incarceration. For example, incarceration information may include booking date, charges, convictions, gang affiliations, disciplinary actions, historical confinement of the inmate, list of inmate's violations of regulations of the controlled facility, account balance for payment of communications, and other information.

Continuing with the discussion regarding the database server (702), the audit data (714) includes information stored for auditing purposes. For example, for each communication, the audit data may include timestamps defining when the third party call was performed, detected individuals on the call, telephone numbers on the call, length of the call, a unique identifier of the communication device used in the call, and other tracking information about the call. Saved communications (716) correspond to transcripts and/or recordings of the multiparty call.

In one or more embodiments of the invention, party voiceprint data (718) corresponds to known voiceprints related to the individual having the voiceprint. For example, voiceprint data (718) may include voiceprints for present and past inmates of the controlled facility and other controlled facilities, voiceprints of judges and prosecutors, and other information.

Although FIG. 7 shows a certain configuration of components, other configurations may be used without departing from the scope of the invention.

FIGS. 8-10 show flowcharts in one or more embodiments of the invention. While the various steps in these flowcharts are presented and described sequentially, some or all of the steps may be executed in different orders, may be combined or omitted, and some or all of the steps may be executed in parallel. Furthermore, the steps may be performed actively or passively. For example, some steps may be performed using polling or be interrupt driven in accordance with one or more embodiments of the invention. By way of an example, determination steps may not require a processor to process an instruction unless an interrupt is received to signify that condition exists in accordance with one or more embodiments of the invention. As another example, determination steps may be performed by performing a test, such as checking a data value to test whether the value is consistent with the tested condition in accordance with one or more embodiments of the invention.

FIG. 8 shows a flowchart for creating a multiparty call by adding parties to an existing call in one or more embodiments of the invention. In Step 801, a two-way call is established between an inmate and another party in accordance with one or more embodiments of the invention. For example, the inmate may authenticate him or herself to the network application. The inmate may receive the call or place the call in one or more embodiments of the invention.

In one or more embodiments of the invention, a determination is made whether a request is received to add a party to the call in Step 803. Specifically, the inmate may indicate a request to add a party to a call during the call. For example, the inmate may flash the switch hook (e.g., by depressing the switch hook for a predefined period of time). The connection module may detect the flashing of the switch hook and temporarily suspend the call. The connection module may prompt the inmate with instructions for adding another party to the call.

In Step 805, a determination is made whether to use the inmate's telephone network list in one or more embodiments of the invention. For example, the inmate may select to communicate with an existing contact. In one or more embodiments, an inmate telephone network list is presented to the inmate in Step 807. For example, if the inmate is performing the call through an inmate kiosk, the inmate telephone network list is displayed for the inmate. By way of another example, if the call is through an inmate telephone, the inmate telephone list may be audibly played for the inmate. The connection module may optionally use caller ID, or reverse-number lookup databases to assign a name to each number, and then use text-to-speech conversion to read the name of each number to the inmate in one or more embodiments of the invention. As an alternate example, the inmate may simply press the star button to temporarily suspend the call and cause the connection module to prompt with instructions to add another party to the call.

In Step 809, a selection of a contact is received from the inmate telephone network list in accordance with one or more embodiments of the invention. For example, the inmate may dial as short speed dial code that is one digit in the range of 2-9, or two digits in the range of 20-49. By way of another example, if the inmate is using a kiosk, the inmate may select a button corresponding to the contact. Although not shown in FIG. 8, when the selection is received, a determination may be made whether the contact is unprocessed, filtered, or approved in one or more embodiments of the invention. If the contact is unprocessed, in some embodiments, the contact may be filtered and, if the contact is not prohibited, then the contact is approved. In some embodiments, a contact may need to be additionally vetted to be approved. In one or more embodiments of the invention, once a contact is approved, information about the approval may be stored in the datacenter server and the contact does not need to be reapproved for subsequent communication.

Returning to Step 805, if the determination is made not to use the inmate's telephone network list, then a new number is received from the inmate in Step 811. In Step 813, the owner of the number is identified. Determining the owner may be performed by performing a reverse phone number lookup search to identify the owner. If the owner cannot be identified from a reverse phone number lookup, the addition of the new party may be denied in one or more embodiments of the invention.

In Step 815, if the owner is identified, a determination is made whether the number is authorized in accordance with one or more embodiments of the invention. For example, a determination may be made as to whether the inmate may connect to the owner. Determining whether the inmate may be performed by comparing the owner to an unauthorized list, such as known gang members, judges, jury, prosecutor, witnesses, victims, or other individuals. If the number is not authorized, then the inmate may be notified of the lack of authorization and prohibited from completing adding the new party.

In Step 817, if the number is authorized, the new party is contacted for the call in accordance with one or more embodiments of the invention. Specifically, the number may be dialed or otherwise connected.

In Step 819, the new party is informed of the call being a call with a controlled facility. Specifically, the new party may be performed prior to the inmate being able to communicate with the new party. The information may include, for example, that the call is subject to monitoring and recording. Further, the connection module may ask the party to accept or reject the call (e.g., by using a touch-tone keypad). In Step 821, a determination is made whether the new party accepts. If the new party does not accept, then the party is not added to the call.

In Step 823, if the party accepts, then a determination is made whether the party that answered is authorized in accordance with one or more embodiments of the invention. For example, the party that answered may not be the owner of the telephone number to the call. In such a scenario, embodiments may request the party's name or use voiceprint technology to determine whether the party is authorized. Further, determining whether the party is authorized may be performed by determining whether or not the party is prohibited. Specifically, one or more embodiments may use a prohibited list and allow parties who are not on the list. Alternatively or additionally, one or more embodiments may used an allowed list and deny parties not on the list.

If the party that answered is not authorized, then the party may not be added to the multiparty call. If the party is authorized, the new party is connected to the existing call in Step 823 in one or more embodiments of the invention. In one or more embodiments of the invention, the inmate may optionally continue adding parties to the call.

FIG. 9 shows a flowchart for establishing a multiparty call in one or more embodiments of the invention. Specifically, FIG. 9 shows a flowchart for an inmate to specify at the beginning that a call is to be a multiparty call in accordance with one or more embodiments of the invention.

In Step 901, a request for a multiparty call is received from an inmate in accordance with one or more embodiments of the invention. For example, the inmate may access the network application, authenticate him or herself to the network application, and select a menu option to create a multiparty call.

In Step 903, a party identifier is received for each party to the call in accordance with one or more embodiments of the invention. Specifically, the inmate may specify each party to the call. Receiving a party identifier may be performed in the same or similar manner to performing Steps 807, 809, and 811 of FIG. 8 as described above.

In Step 905, verification that the inmate is authorized to communicate with each party to the call is performed to obtain verified parties. In one or more embodiments of the invention, each party is verified independently. If a party is unauthorized, then multiparty call may proceed without the party. Alternatively, the inmate may be notified that a particular party is not permitted to join and the inmate may decide whether to proceed without the party. Verifying parties to the call may be performed in the same or similar manner to performing Steps 813, 815 and 823 of FIG. 8 as described above.

In Step 907, an attempt is made to connect to verified parties in accordance with one or more embodiments of the invention. In particular, the number of the party may be dialed. If the party does not answer or does not accept, the call with the party fails. Steps 905 and 907 may be performed in parallel. For example, a first verification may be performed based on the owner of the telephone number and a second verification may be performed based on the party that answered the telephone number.

In Step 909, an inmate is informed of the status of connecting parties to the call in accordance with one or more embodiments of the invention. In one or more embodiments of the invention, the inmate may be informed as to how the call is proceeding. For example, while the parties are connected, authentication, and authorization checks are being performed, the inmate may be kept apprised of the status, and optionally be presented with music-on-hold to keep him or her comfortable. In the example, as each party is confirmed, the network application may announce the success of the connection, state the party's name (e.g., by their recorded name or by text-to-speech), and then connect the call. Further in the example, upon denial of any party or failure of the party to answer, the network application may announce the failure. In the example, upon having authorized or denied all desired parties, the network application may announce that all available and permitted parties are connected. The network application may then remain virtually silent for either the rest of the call, or until the inmate initiates a touch-tone command to perform such tasks as removing parties from the call, or performing other operations.

FIG. 10 shows another flowchart for establishing a multiparty call in accordance with one or more embodiments of the invention. In FIG. 10, a conference line is used. In Step 1001, a request from an inmate for a multiparty call is received in accordance with one or more embodiments of the invention. Receiving a request may be performed in the same or similar manner to Step 901 in FIG. 9 discussed above.

In Step 1003, a conference line for a multiparty call is generated in accordance with one or more embodiments of the invention. Specifically, a number is selected for all parties to call in. The number may be a toll number, such that each party pays for part of the call in accordance with one or more embodiments of the invention. Alternatively, a toll-free number or local number may be used.

In Step 1005, a verification that the inmate is authorized to communicate with each party to the multiparty call is performed to obtain verified parties. Verifying parties may be performed in the same or similar manner to Step 905 in FIG. 9 discussed above.

In Step 1007, the conference line is sent to each party and to an administrator in accordance with one or more embodiments of the invention. For example, the conference line may be emailed to each party. By way of another example, each party may receive a text or voice message with the conference line. In one or more embodiments of the invention, the administrator added to the call may serve as a moderator on the call. For example, the administrator may listen to the subject matter of the call and control the audio of the call.

In Step 1009, connections of the parties are received. Specifically, each party calls in to the conference line. In Step 1011, the administrator on the call is confirmed. In one or more embodiments of the invention, the inmate may be prohibited from communicating in a multiparty call until an administrator is on the call. Thus, the administrator's presence may be verified before the call proceeds. Once the administrator's presence is verified, the call may proceed.

FIG. 11 shows a flowchart for controlling and analyzing a call in accordance with one or more embodiments of the invention. In Step 1101, a controlled facility tone is transmitted during the call in accordance with one or more embodiments of the invention. Various techniques of tone generation and detection may be used. The various techniques may be coordinated amongst all or a portion of the controlled facility using tonal generation and detection.

For example, in a first technique, multiple notch filters are used in a coded pattern, unique to each controlled facility, terminal, inmate, or other in accordance with one or more embodiments of the invention. To identify incoming calls from a controlled facility, the multiple notches may be removed from incoming audio generated originating from controlled facilities to obtain identifying patterns. Details about each pattern may be stored in a data repository that is indirectly or directly available to controlled facilities. Thus, the identifying pattern in incoming audio may be detected and compared with stored patterns in the data repository. In one or more embodiments of the invention, tones are selected so as to not result in destructive interference when incoming audio is from multiple controlled facilities. In such a scenario, pattern matching may be used to distinguish each tone.

By way of another example technique, a continuous and scarcely audible set of tones are generated, with pre-defined patterns for each facility. For example, such tones may be at each edge of the telephony band pass filters. In such a scenario, because of constructive and/or destructive interference effects, the audio on the channel (e.g., incoming audio and outgoing audio) is changed when more than one similar tone is present.

In one or more embodiments, the tone may include information about the call, such as the vendor who added the tone to an inmate call, a unique identifying number identifying the stored communication in the datacenter server, an identifier of the inmate, a location of the phone or kiosk, an original dialed number, and/or other information

In Step 1103, incoming audio is tested for a controlled facility tone in accordance with one or more embodiments of the invention. Testing the incoming audio may be dependent on the technique as discussed above. If incoming audio is positive for a controlled facility tone, then the system may detect that at least the same or different controlled facility is also on the line. For example, two inmates in the same controlled facility may be attempting to communicate via a third party. Alternatively, inmates in different controlled facilities may be attempting to communicate via a third party. In such a scenario, the communication may be a violation of a rule of the controlled facility.

Although not presented in FIG. 11, outsiders or investigators may use the controlled facility tone to detect when a call includes an inmate in a controlled facility. For example, the inmate may attempt to bypass detection by making the call through a third party, who then conference calls the outsider. However, the call, which is now a multiparty call, includes the tone from the controlled facility. By comparing the tone with stored tones, the outsider may detect that the inmate is present. Thus, one or more embodiments may prevent the inmate from calling outsiders, such as judges, jury members, witnesses, victims, and others.

In Step 1105, a call fingerprint is generated for the call in accordance with one or more embodiments of the invention. Generating a call fingerprint may be performed by storing a short segment of the call separate and distinct from the stored communication. The short segment may be, for example, a five second segment, a twenty second segment, a thirty second segment, etc. Further, multiple segments may be grouped to create the fingerprint. For example, segments gathered from the beginning and middle of each minute may be grouped to create a call fingerprint.

In Step 1107, the call fingerprint is compared with call fingerprints from other facilities to determine whether inmate is improperly calling another facility. In order to reduce the number of comparisons, the call fingerprint may be compared with call fingerprints generated from calls in the same time range as the original call. For example, the call fingerprints generated within minutes, hours, or days from each other may be compared. Thus, one or more embodiments may detect when an inmate is having a message recorded by a third party, which is then played for another inmate. In such a scenario, the communication may be a violation of a rule of the controlled facility.

In Step 1109, data mining on connection parameters of the call is received in accordance with one or more embodiments of the invention. Data mining includes analyzing the connection parameters of the call to detect patterns. For example, the connection parameters that are analyzed may include one or more of the following: a list of all authenticated parties on the communication, a list of voiceprint identifiers and probable individuals that match the voiceprints on the communication, timestamp for the beginning and end of the communication, timestamps for any multiparty call detection events, a list of all telephone numbers or other telecommunications addresses officially connected to the conversation, any dual tone multi-frequency (DTMF) digits detected during the communication, credit card information used to pay for the communication, whether any alarms or flags were set on the communication, which telecommunications carrier was used, investigator notes, language used, call termination status, and other such data.

In one or more embodiments of the invention, the call analysis module may check for a variety of different patterns. For example, the pattern may be one or more inmates who regularly call a specific number at a specific time of day. By way of another example, the pattern may be the same destination telephone number or other telecommunication address having been connected to or from any multiple kiosks or inmate phones. Another example pattern may be non-overlapping calls to the same number, and from multiple inmates, within a specified period of time. Such pattern may indicate that a message might be being relayed verbally by outside parties. By way of another example, the call analysis module may compare suspicious calls, such as calls lasting only a couple of minutes, then check for commonality of connection parameters.

In one or more embodiments of the invention, the pattern detection may be performed, for example, at the outside facility that may service multiple controlled facilities. Specifically, the outside facility may analyze the connection parameters of each of the calls to and from various controlled facilities to detect the patterns. The detection may be in real-time during the call or after the call.

If a pattern is detected, the communications having the pattern may be a violation of a rule of the controlled facility.

In Step 1111, voices on the call are analyzed to determine whether an unauthorized party is on the call in accordance with one or more embodiments of the invention. Specifically, voiceprints of voices on the call may be compared to stored voiceprints. If a match is found, then the individual matching the stored voiceprint is identified. A determination may be made whether the inmate is permitted to communicate with the individual. If the inmate is not permitted to communicate with the individual, then the communication may be a violation of a rule of the controlled facility.

In Step 1113, discussion in the call is analyzed to determine whether improper communications are being performed by the inmate in accordance with one or more embodiments of the invention. For example, the analysis may be performed to detect whether the subject matter of the call is regarding a crime, or if vulgarity, obscenity, nudity, or other such improper communications are transmitted in the call. Specifically, the analysis may be based on the words of the call (e.g., by comparing the words transmitted on the call with known words), visual transmissions (e.g., doing an image analysis to test for nudity or other improper gesture), or other technique. The call analysis module may perform the comparison. Alternatively, a reviewer on the call may perform the comparison. In one or more embodiments of the invention, a user interface may display gang symbols and criminal imagery to guide the reviewer into what constitutes improper communication. Improper communications may be deemed a violation of a rule of the controlled facility.

In Step 1115, a determination is made whether an improper communication is detected in accordance with one or more embodiments of the invention. Specifically, a determination may be made whether any of the tests described above are improper in one or more embodiments of the invention. If an improper communication is received, a notice is transmitted to the investigator in Step 1117 in accordance with one or more embodiments of the invention. The notice may include the rule that was violated, identification of the communication, information about the part of the communication that violated the rule, and/or other information in one or more embodiments of the invention. Additionally or alternatively, the multiparty call may be disconnected in accordance with one or more embodiments of the invention.

In one or more embodiments of the invention, all or a portion of the analysis described in FIG. 11 may be performed. Specifically, some steps of FIG. 11 may be omitted or performed in different orders. Further, one or more steps may be repeated throughout the call in one or more embodiments of the invention. The various analysis may be performed in real-time, during the communication, and/or after the communication completes.

The following is an example in accordance with one or more embodiments of the invention. In the following example, consider the scenario in which Ralf, a hardened criminal in a Texas prison and member of Ruff Gang learns from family members that his house was robbed. He also learns that the thief is being held in a California jail. Knowing that his fellow Ruff Gang member Tony is also in the same California jail, Ralf wants Tony to murder the thief while in jail. However, Ralf knows that inmate-to-inmate communication is prohibited where the inmates are in different controlled facilities. Both Ralf and Jim share a friend in common who is not in jail, and the friend coordinates with the two inmates for them both to call him on his cell phone at roughly the same time. The friend accepts both calls, and then opts to merge the calls, which is a common option on modern mobile phones. The two inmates are then bridged together and they can speak freely to each other to coordinate the murder attempt. Unbeknownst to all parties, the two inmates' calls were accompanied by an inaudible, or barely audible tone that identifies the prisons from which the calls originated. Thus, even though the calls are not directly connected to each other (i.e., the calls are bridged), the system is still capable of detecting that an inmate-to-inmate call is occurring. The system may be configured to disconnect the call immediately, but in this case, the call sets off an alert to investigators and the call is allowed to continue for evidence. The investigator is able to listen to the call while it is occurring, such as via a Web-based administration system, and download the call afterward. Through the information in the tones, the investigator has name of both facilities and inmates, and she able to thwart the murder plan.

 2. The method of claim 1, further comprising: transmitting, by the first controlled facility, a second controlled facility tone on the call during the call, wherein the second controlled facility tests received audio for the second controlled facility tone.
 3. The method of claim 1, further comprising: generating a call fingerprint from audio in the call; comparing the call fingerprint with a plurality of call fingerprints from a plurality of controlled facilities; and transmitting a notification of a second violation when the call fingerprint matches at least one of the plurality of call fingerprints.
 4. The method of claim 1, further comprising: verifying each party to the call by: obtaining an owner of a telephone number of each party to the call; and verifying that the inmate is authorized to communicate with the owner, wherein connection of the telephone number to the call is denied when the inmate is not authorized to communicate with the owner.
 5. The method of claim 1, further comprising: for each party of the call, obtaining, during the call, a voiceprint of the party; and verifying that the inmate is authorized to communicate with the party having the voiceprint, wherein connection of the party to the call is suspended when the inmate is not authorized to communicate with the party based on the voiceprint.
 6. The method of claim 5, wherein obtaining the voiceprint and verifying the inmate is authorized is performed periodically for each party of the call throughout the call.
 7. The method of claim 1, further comprising: analyzing a discussion performed over the call to determine the subject matter of the discussion; determining, based on the subject matter, whether a second violation is occurring; transmitting a notification of the second violation when a second violation is occurring.
 8. The method of claim 1, further comprising: analyzing a discussion performed over the call to determine the subject matter of the discussion; determining, based on the subject matter, whether a crime is being discussed; transmitting a transcript of the call to an investigator when a crime is being discussed.
 9. The method of claim 1, further comprising: obtaining connection parameters from the call; performing data mining on connection parameters to determine whether the call violates a rule; and transmitting a notification of the a violation when the call violates a rule.
 10. A system for controlling a call in a first controlled facility, comprising: a computer processor; and a network application executing on the computer processor and comprising: a connection module configured to connect an inmate in the first controlled facility to the call when each party of the call is verified; and a call analysis module configured to: test incoming audio on the call to detect a first controlled facility tone from a second controlled facility, and transmit a notification of a first violation by the inmate when the first controlled facility tone is detected in the incoming audio.
 11. The system of claim 10, wherein the call analysis module is further configured to: generate a call fingerprint from audio in the call; compare the call fingerprint with a plurality of call fingerprints from a plurality of controlled facilities; and transmit a notification of a second violation when the call fingerprint matches at least one of the plurality of call fingerprints.
